CHICAGO (AP) — Vice President Kamala Harris called on Americans to join her to “chart a new way forward” as she accepted the Democratic nomination on Thursday, arguing her personal story and prosecutorial background made her uniquely qualified to protect their interests and beat Republican Donald Trump.

Taking the stage to a thunderous standing ovation at the Democratic National Convention in Chicago, Harris sought to introduce herself to the American public and outline her vision for leading the nation for the next four years.

“Our nation with this election has a precious, fleeting opportunity to move past the bitterness, cynicism, and divisive battles of the past,” Harris said. “A chance to chart a new way forward. Not as members of any one party or faction, but as Americans.”

Harris’ address in Chicago caps a whirlwind eight weeks in American politics and manifests the stunning reversal of Democratic fortunes just 75 days until Election Day. Party leaders who had publicly despaired over President Joe Biden’s candidacy after his disastrous debate against Trump, were jubilant both at the historic nature of Harris’ candidacy and their buoyed hopes for this November.

The daughter of Jamaican and Indian immigrants, Harris became the first Black woman and person of South Asian descent to accept a major party’s presidential nomination. If elected, she would become the first female U.S. president.

“America, the path that led me here in recent weeks was no doubt unexpected. But I’m no stranger to unlikely journeys,” she said.

Harris talked about being raised primarily by her mother after her parents divorced in a small apartment in San Francisco’s East Bay, and being raised as well by friends and caregivers who were “family by love.” She also detailed a key part of her political origin story, when Wanda, her best friend from high school, confided in her that she was being abused by her stepfather and came to live with Harris’ family.

“That is one of the reasons I became a prosecutor. To protect people like Wanda,” Harris said.

Outlining her career as a prosecutor, state attorney general, senator and now vice president, Harris said, “My entire career I’ve only had one client: the people.” Meanwhile, she said Trump has only ever acted in the interests of “the only client he has ever had: himself.”

As she took the stage, she saw a sea of female delegates and Democratic supporters wearing white — the color of women’s suffrage — the movement that culminated with American women securing the right to vote in 1920.

A festive mood filled the United Center all evening, with a packed audience including running mate Tim Walz dancing and singing along to a mix of pop and classic rock. Two of Harris’ young grandnieces were brought onstage by actress Kerry Washington to remind the convention how to correctly pronounce her first name. At the girls’ direction, one side of the arena shouted “comma” and the other “la.”

Harris made a direct appeal to anti-Trump Republicans to put aside party labels and to support her over Trump, who denied his loss to Biden in the 2020 election, which inspired the Jan. 6 2021 Capitol insurrection.

“I know there are people of various political views watching tonight, and I want you to know I promise to be a president for all Americans,” Harris said. “I promise to be a president for all Americans to hold sacred America’s constitutional principles, fundamental principles, from the rule of law and fair elections to the peaceful transfer of power.”

The prosecutor in Harris surfaced during the speech when, in referring to Donald Trump, she referred several times to “his explicit intent” to free those who assaulted law enforcement officers at the Capitol, jail political opponents, and use the military against American citizens.

“Consider what he intends to do if we give him power again,” she added.

Despite speculation about a potential surprise appearance by the music superstar Beyoncé at Thursday’s convention ahead of Harris’ speech, a source involved in the evening’s planning who was not authorized to discuss it publicly said she would not be in attendance.
